BMW 4.8is X5 Running lumpy from cold start

2 posts in this topic

I have a BMW 4.8is and when i start it first thing in the morning it runs terribly lumpy and the emissions light comes on. It does this for about 2 minutes then its fine for the rest of the day. It has been to BMW 3 times and they cant seem to sort it so it is going back again! Didnt know if any of you guys had experienced the same thing or could shed any light on the subject?
